Papillary tumor

Papillary Tumor

A papillary tumor is a type of neoplasm that has a characteristic papillary architecture. The term "papillary" refers to the tumor's growth pattern, which resembles small, finger-like projections or papillae. Papillary tumors can occur in various parts of the body, including the thyroid gland, kidneys, bladder, and breast.

Characteristics

Papillary tumors are typically characterized by their distinct papillary structures. These structures are formed by proliferating cells that create a fibrovascular core, which is then covered by a layer of neoplastic cells. The presence of these papillary structures is a key factor in the diagnosis of papillary tumors.

Types of Papillary Tumors

Papillary Thyroid Carcinoma

Papillary thyroid carcinoma is the most common type of thyroid cancer. It is typically slow-growing and often presents as a painless mass in the neck.

Papillary Renal Cell Carcinoma

Papillary renal cell carcinoma is a type of kidney cancer that arises from the renal tubular epithelium. It is the second most common type of renal cell carcinoma.

Papillary Urothelial Carcinoma

Papillary urothelial carcinoma is a type of bladder cancer that originates from the urothelial lining of the bladder. It is characterized by the presence of papillary structures on the surface of the tumor.

Papillary Breast Cancer

Papillary breast cancer is a rare type of breast cancer that is characterized by the presence of papillary structures. It is typically less aggressive than other types of breast cancer.

Diagnosis and Treatment

The diagnosis of a papillary tumor typically involves a combination of medical imaging, biopsy, and histopathology. Treatment options for papillary tumors depend on the location and stage of the tumor, and may include surgery, radiation therapy, and chemotherapy.
